The memo states that 93 arrest warrants were issued for 31 people and said warrants would be processed for 10 additional people. However, the document only lists 21 names.

Fort Worth police spokesman Sgt. Pedro Criado said he could not comment on the possibility of any additional arrests but clarified that the total number was 31 people.

The police memo is an "after action" report written five days after the raid. It was obtained by NBC 5 on Wednesday after being requested under the Texas Open Records Act. (Read the report here.)

At a news conference on Feb. 15, just hours after officers rounded up suspects on and near campus, police announced a total of 17 arrests. At least three others who did not have warrants were arrested during the raid.

"On the day of execution, we were targeting the 18 listed, with warrants for two additional that we knew weren't in the area," Criado said.

He said one suspect turned himself in on Feb. 17.

The report also reveals police seized:

Nine weapons

$46,243 in cash

$29,000 in marijuana, prescription pills, cocaine and methamphetamine

15 vehicles worth $253,890

Officers found a half-ounce of marijuana, a digital scale and five drug pipes in a search of Tanner Brock's house just off-campus, the memo said.

Brock, a standout linebacker on TCU's football team, was one of four players arrested in the sweep.
